How to correctly define the efforts in the elements of the farm
Determination of efforts in the elements of the farm during nodal load is carried out by the usual methods of construction mechanics.
Found efforts in the elements of the farm from constant and temporary, as well as from unprofitable combinations of loads are recorded in the free table. If an extra -air load is applied to the upper or lower waist of the farm, then the bending moments in the belt are determined as for an unreasonable beam. The sizes of spans of such a beam are taken equal to the distance between the nodes. When determining the bending moments from the extracurricular load in the upper belt of the arched farm, it is necessary to take into account the unloading influence of the eccentricity of the longitudinal force.
The calculation of the bearing capacity of the sections of the farm elements is made depending on the efforts arising in these elements, you can find out more about screw stilts on the site.
